HELP! I upgraded to 8.1, now XP doesn't open on VirtualBox, any suggestions?
Could not start the machine Windows XP because the following physical network interfaces were not found:
Realtek PCIe GBE Family Controller (adapter 1)
You can either change the machine's network settings or stop the machine.
Failed to open a session for the virtual machine Windows XP.
Nonexistent host networking interface, name 'Realtek PCIe GBE Family Controller' (VERR_INTERNAL_ERROR).
